The Brief
Competing in a Crowded Market
The client's users were already searching flights and hotels on established apps. To earn their switch, the new app needed faster search, stronger personalization, and a booking flow that stayed out of the user's way.

Engineering Challenges
What Shaped Every Decision
The build had to balance real-time travel data, peak-season scalability, and reliable booking transactions so users could search, compare, and confirm trips without delays or failed flows.
Six APIs, One Coherent UI
Each provider used different schemas, rate limits, and update cycles. Surfacing accurate, unified pricing without saturating API quotas needed a purpose-built aggregation layer.
✓ Provider schema differences
✓ Rate-limit safe search logic
✓ Resolution
Centralized sync engine with per-provider TTL caching and schema normalization. One clean data contract for the UI regardless of provider differences.
10× Traffic in Hours
Holiday fare sales and seasonal peaks arrive without warning. An app that slows during a sale loses the users it spent months acquiring. Fixed capacity was not viable.
✓ Peak-season traffic spikes
✓ Cloud capacity planning
✓ Resolution
Auto-scaling cloud clusters with database read replicas and CDN distribution. Load tested at 15× production traffic before every release.
Bookings That Cannot Fail
A dropped transaction, network timeout, concurrent modification, or provider delay can create refunds and lost users. The system had to handle partial failures safely.
✓ Safe payment and booking flow
✓ Delayed provider confirmation
✓ Resolution
Idempotent APIs with optimistic inventory locking and provider webhooks for delayed confirmations. No lost state on reconnect.
Core Features
Search to Confirmed Booking
40 user interviews before a line of production code shaped every flow. Every screen was designed to reduce the steps between a search and a confirmed trip.
✓ Real-time flight search
✓ Hotel booking & comparison
✓ Multi-city itinerary builder
✓ Offline access to saved trips
✓ Personalized recommendations
✓ Multi-currency in-app payments
Simple Navigation
Minimal steps from search to booking across all user types.
Unified Listings
Live results from multiple providers with instant filters.
Destination Discovery
Curated guides and personalized suggestions by trip type.
Trip Planner
Drag-and-drop itinerary builder with conflict detection.
Technical Stack
Each Service Scales Independently
The travel platform was built with a modular architecture so search, booking, payments, data sync, and user services could scale without slowing each other down.
Mobile
Cross-platform app development with platform-native UX on iOS and Android.
Backend
Microservices with GraphQL gateway for search, booking, users, and notifications.
Infrastructure
Auto-scaling clusters with CDN and read replicas tuned for seasonal traffic.
Data Layer
Sync engine normalising six provider feeds with per-type TTL caching.
Payments
Idempotent transactions with multi-currency support and full audit trail.
Security
Biometric authentication, encrypted payment flows, and PCI-DSS compliance.
✓ Architecture designed for independent scaling, faster releases, and safer travel booking operations.
The Turning Point
One Prototype Finding Changed the Outcome
User testing exposed the exact checkout friction point before engineering began, helping the team simplify the booking flow with confidence.

Choose Pay Done
Prototype Insight
The original checkout required seven steps. Users were abandoning at step four.
User testing in week five of prototyping revealed that travellers expected to go from search to confirmed trip in as few taps as possible. The existing flow payment, traveller details, add-ons, review, confirm, verify email, final confirm felt like a form.
Collapsing it to choose, pay, done was validated with users before development started. At launch, the redesigned flow produced a 42% increase in conversion rate the largest performance gain at launch.
